Today, the moon will reach its fullest phase at 8:37 a.m. EDT (1237 GMT). Unfortunately, there won't be a gorgeous robin's-egg orb in the sky the night before Easter (PSA: Easter is this Sunday), just a typical, pearly grey full moon. The first blue moon of 2018 occurred on January 31st. A blue moon means it is the second full moon to occur in a month; a supermoon means a full moon which is closest to the Earth.
As explained by NASA, the common definition of a blue moon is a second full moon in a single month.
The term "blue moon" has been around since the 1940s.
At the time of this Moon, the ground begins to soften enough for earthworm casts to reappear, inviting the return of robins and migrating birds-a true sign of spring. The event can happen once in 2.66 years and whenever it takes place, the second full moon is called the "Blue Moon".
When can I see the blue moon?
What is a blue moon? This Blue Moon will rise during the Easter weekend, thereby becoming a Paschal Moon, Space.com notes in a separate article. In some years, Paschal moon is usually designated as Easter Sunday and 2018 is one of those years.
But with that in mind, we'll happily celebrate the extra full moon in a month or in a season variety. Also, February, which has only 28 or 29 days (during leap years), will never have a Blue Moon. "The next time there will be no full moon in February will be 2037".
The monthly blue moon is the second full moon in a month with two full moons.
Because a blue moon is quite rare, the lunar event helped to coin the saying "once in a blue moon".
A "worm moon" rose on March 1, and a rare parade of planets, including Jupiter, Mars, Saturn, Mercury and Venus along with the bright star Antares, lit the sky from March 7 through March 11. The moon will be visible in United Kingdom at 7:30pm.
